Here, we describe a rule-based machine translation system that translates English sentences to the Igala language. This work was evaluated with respect to adequacy, a measure of the quantity of information existent in the original text that the translated text contains. It indica...

Visualizing volumetric datasets using real-time volume rendering technique involves a large number of interpolation operations that are computationally expensive. This situation used to restrict real-time volume rendering methods to be used only on high-end graphics workstations...

This paper solves a stochastic three-level decision maker’s model. This approach uses stochastic parameters in the objective function to solve a three level quadratic programming problem. The probabilistic nature of the objective functions is converted to an equivalence determini...

Assuming the conjecture that all effectively calculable functions must be Turing-machine computable, this paper demonstrates that the problem of recognizing Fibonacci numbers must be in general undecidable. This means that there is no algorithm, which in a finite number of steps...

In this paper we leave the neighborhood of the singularity at the origin and turn to the singularity at the horizon. Using nonlinear distributional geometry and Colombeau generalized functions it seems possible to show that the horizon singularity is not only a coordinate singula...

Tobin's one-fund theorem states that, when a portfolio is consisting of some risky assets and a riskless asset (with return rc), then every ecient portfolio in the Mean-Variance optimization is a combination of the tangency portfolio and the riskless asset. We introduce the notio...

Two di erent approaches are applied to solve high-order integro-di erential equations (IDEs), based on Radial Basis Functions (RBF). The rst approach, which is called the direct approach (DRBF) is based on di erentiation, and considers the solution as a nite linear combination of...

According to the higher computational complexity during the training process of sparse representation, the centers of granular computing (GrC) with L1-norm are regarded as the bases of sparse representation and used to reconstruct the super-resolution image of input image. Firstl...

In this paper, we propose an efficient algorithm to decompose a directed acyclic graph G into a minimized set of node-disjoint chains, which cover all the nodes of G. For any two nodes u and v on a chain, if u is above v then there is a path from u to v in G. The best algorithm f...
